So i was wondering how to properaly fit some computer fans in a terra...Now the problem is that i have such a high humidity that i am afraid the fans won't last long.I will fit 1 blowing and 1 sucking the air out of the terrarium so it will cool properaly.The fans output and input would come in a sheet of plexiglass on top of the terra.The terra is an old aquarium of 1.2m. long so i can't drill holes in the sides of it of course...on top of the plexi glass sheet there is a wood cover with two big groluxes in it.
